OlL-SEPARATOR.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed December 11, 1903. Serial No. 184,766.

To all whom it may concern:

Be it known that I, VVILHELM Bn'rzow, a resident of Dusseldorf, in theKingdom of Prussia, German Empire, have invented new and usefulImprovements in Oil-Separators for Steam, of which the following is aspecification.

The present oil-separator belongs to that kind of devices in which steamholding oil is conveyed into a receptacle provided with plates, bars,troughs, or the like, which are adapted to separate the oil from thesteamcurrent. In all hitherto-known arrangements of this kind theseparation of the oil has to take place within the steam-receptacle andsteam-current, there being no special devices to support theinstantaneous separation of the oil from the steam-current andto leadthe separated oil away. The oil and oil-water therefore always remainmore or less within the steam-current, and the latter draws the sameagain with it, so that the effect of this apparatus is actually quiteimperfect. The present oil-separator differs from all these well-knownapparatus so far as there is a special accumulator or receptaclearranged in the steam-drum. The oil or oil-water, respectively, on beingseparated from the steam by specially-formed separating devices, asplates, bars, or troughs arranged within the steam-drum, is immediatelyand some way positively conveyed into said oil-receptacle, and thus outof the course of the steam-current, whereby a perfect separation of itfrom the steam is insured.

The invention is illustrated in the accompanying drawings, in whichsimilar letters denote similar parts.

Figure 1 shows a vertical section of the steam-drum with theoil-separator arranged therein. Fig. 2is also a vertical section showingthe arrangement of the troughs within the steam-drum. Fig. 3 is across-section of the steam-drum. Fig. 4 is a detail part, showing across-section through the trough; and Fig. 5 is a scheme of my newoil-separator, showing the way of the steam passing through.

a is a steam-drum, having an inlet Z2 and an outlet 0. The oil-separatormay, as stated above, consist of plates, bars, or preferably, as shown,of U-shaped troughs (Z, the top edges 6 of which are bent over, as shownin Fig. 4c. These troughs are arranged at the side of each other in rowsand alternatively one above the other, Figs. 1 and 2, and are on one endapplied to the wall of the drum or to an intermediate piece arrangedwithin the drum and on their other end terminate into receptacle f. Thisreceptacle f is entirely closed from all sides and on its bottom it hasan opening which registers with an outlet 9, arranged in the bottom ofthe drum.

It is obvious that the steam holding oil when entering the drum throughI) and flowing over the troughs will be deprived of the oil, and the oilor oil-water gathering in the troughs will immediately flow along thesetroughs into the receptacle f, wherefrom it may then be dischargedthrough the outlet 9.

It has been found advantageous to cover the troughs on their outsidewith felt it, as seen from Fig. 4, and to arrange a partitionwall 71,Fig. 1, within the oil-receptaclef.

Owing to the fact that in the present arrangement all troughs have theiropen side turned toward the steam-current and are alternatively arrangedunderneath each other and terminate into a mutual oil-receptacle intothat the exhaust-steam cannot pass, owing to the vacuum of thecondensation, the steam will become perfectly separated from the oil.

Having now particularly described and ascertained the nature of myinvention and in what manner the same is to be performed, I declare thatwhat I claim is In an oil-separator for steam the combination of troughsarranged in series at the side of each other and alternatively one abovethe other within said drum, one end of said troughs being suitablyattached to a partitionwall and the other to the wall of anoil-receptacle entirely closed from all sides and provided on its bottomwith an opening which registers with an outlet in the drum-bottom, thetroughs all terminating into that receptacle, substantially as describedand shown and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.

IVILHELM BIITZOW.
